Can you help me, I do not know what to do; i plugged too many things in and the fuse blew?

First off you should have devices plugged into a power strip. You also need to only plug in what you are using I am sure you do not play xbox and ps3 at the same time! Open the circuit panel and look for the breaker that not lined up with the others move it to the off position and then the on position .If you cannot figure out which one it is then switch each one at a time,once you find it mark it with a piece of tape so you know for next time.Good Luck
